The present invention relates to an improvement on the common type of fertilizer disk mixer now in use particularly for potato planters.

The ytype now in common use has the disks soarranged that they are pushed along the ground. This type causes a lot of trouble in breakage because whenever an obstacle, a rock for instance is met, the disks frequently and easily break or ifthey do not break, they yfrequently come out of line and cause what 1s commonly known as pairing the rows.

That is, when planting with disks out of line,

the planter plants two rows very close to each other and the next two rwould be far apart and so on.

The prime object of the present invention is to do away with these imperfections.

Another very important object of the invention' resides in the provision of a mechanism of thisnature which is exceedingly simple in construction, inexpensive to manufacture, strong and durable, thoroughly efficient and reliable in use, and operation, and otherwise .well adapted to the purpose for which it is designed. f

' With the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawings:

Figure 1 is a top plan view of the mechanism embodying the features of my invention, l Y

Figure 2 is a side elevation thereof,

Figure 3 is a vertical section through one of the disks,

Figure 4 is a sectional view through the fulcrum bolt and associated parts, c

Figure 5 is a perspective view of one of the hanger bars,

Figure 6 isa sectional view taken substantially on the line 6-6 of Figure 1.

Figure A7 is an enlarged detail elevation showing one of the brackets, and Figure 8 is a perspective view of the cross bar. 1 f

Referring to the drawings in detail numerals 5 indicate the usual bars which are* attached to the pole (not shown) and hold the attachment to the planter (not shown) Sub-k stantially V-shapedhanger bars 6 are bolted or otherwise secured to the bars 5y and have a rod 7 extending through openings 8 in thek apexes thereof.

This rod is secured in place by means of nuts 8; A rocker or lever 9 is rockably mounted intermediate its ends on the'center of the rod 7 and held inthe center by means of spacers `10. Bars ll have openings through which the rod 7 extends at their forward ends,

said forward ends being located between the bars .6 and washers 12 at the outer end of the kspacers 10 and then these bars 11 yconverge inwardly and rearwardly toward each other being securedV to the rear end of theleve'r`9 and extending rearwardly and to their rear endsfisr attached an inverted U-shaped member 14 which extends upwardly and is preferably bolted thereto as at 15. f r

TheV 4portions ofthe bars 1lv extending alongside the rear end ofthe lever 9 have rearwardlyfdiverging brackets 16 secured theretothe reark ends of which terminate in ver-4 tically ydisposed cross platesl?y with a pluralityiof-openings 18 formed therein so that axle-bolts 19-may be ydisposed in any of the openingslS.forfsupporting disks 20 at the desired height.; n

' lChains 21 are connected withthe upper ends'of the plates-lZ-by means of bolts 22 extending through the upper'openings 18 and these chainsare secured to the rear` end portions of the bars 5 in any suitable manner to limit the downward movement of the disks 20.

DisksQO lar'enormally held downwardly as far as allowable by the chains 2l by providing aspring 25 which is anchored on the forward end of the lever20 and adjustably' anchored as at 26 by means of the bolt and thumb nut to the center of a cross bar 27 extending between the forward portions of the bar 5.

Obviously by tightening up on the thumb nut the tension of the spring may be increased and the increasing of the tension of the spring in turn increases the depth at which the disk will cut in the ground while loosening the nor Y nut decreases the tension of the spring and decreases the depth in which the disk will cut. By this arrangement the farmer can plant at any depth desired. Y

Vith this type of mixer it Will be noted that thel disks converge forwardly toward each other andarevv therefore pulled along the ground and have vassociated therewith theV tensonrsprng so that when a rock is reached the spring gives and the disks are rolle/dup v Y over the obstruction.

It Will be further seen that Withmyirn-V proved structure an apparatus is provided Whichis sturdy and has its parts arranged Y Y in an exceedingly compact and convenient manner. f u

It is thought that.V the construction, opera tion, :utility and advantages of this invention will new f'bequite apparent to those skilled this art Without vka more detailed description thereof.. A Y The presenty embodiment of the yinvention has ebeen. disclosed 1 in .considerable @detail merely .tor fther :purposes of exemplification. since inaetual practice it attains the features.

ofi advantage enumerated as desirable in the sta-,tement of the'invention and the above description.

ltvvillhe apparent that changes in the 1de,- tails'oif' construction, and in the Lcombination and arrangement otparts may loe resorted to,

Without .departing from the spirit or scope of 'thev invention as. hereinafter :claimed .or saerilieing any .of its advantages.

Having thusidesclrihed my invention, whatv I claimL as nelvv is;

In an apparatus of thelclass descrihedv, a

trame, .hangers depending from the trame, a rod mounted aero'ssthe lowerportions of the hangers, fa pair' of bars rockable .on the -rod at the ends thereof and converging rearwardlytoivardeach other, avpar of disks, means on the outer side of' each bar orfmeunting'a disk so that they con-verge forwardly :toward each other, a liever?. connected iat .one Lend te the said roclrable bars and ulcrurned atits intermediate portion lon the cen-terni the rod and 'spring meansiconneetedrfwith the vother end of the sa-id lever -to normally urge the disks downwardly, means for-tensioning the spring, -andfan invented U-shaped member hav-ing its ends-seeured to the 'louter .ends of the rockahlesb ars for lexifbly connecting the same. y
